Description
BACKGROUND OF THE INVENTION
The present invention disclosed herein relates to an apparatus for
both humidification and air cleaning.
Air conditioning apparatuses include air conditioners that control
the temperature of air, air cleaners that remove foreign substances
from air to maintain air cleanliness, humidifiers that increase
humidity in the air, and dehumidifiers that reduce humidity in the
air.
Typical humidifiers are classified into a vibration type which
atomizes water on a vibrating plate and discharges it into air and
a natural evaporation type that evaporates water in a
humidification filter.
The natural evaporation type of humidifier is classified into a
disc type of humidifier which rotates a disc using a driving force
and allows water to naturally evaporate from the surface of the
disc in the air and a humidification filter type of humidifier
which allows water to naturally evaporate from a wet humidification
medium by flowing air.
In a typical humidifier, a portion of flowing air during the
humidification process is filtered by a filter. However, since the
main function of a typical humidifier is a humidification function,
its air cleaning function is weak.
Also, since a typical humidifier has a structure in which the
humidification process is performed by adding a filtration
function, a typical humidifier cannot be operated only for air
filtration.
Accordingly, even in a situation where humidity is high, a typical
humidifier inevitably performs humidification even thought a user
desires air cleaning.

A humidification and air cleaning apparatus according to an
embodiment of the present invention may include an air clean module
100 and an air wash module 200 disposed over the air clean module
100.
The air clean module 100 may take in and filter external air, and
may provide filtered air to the air wash module 200. The air wash
module 200 may be supplied with filtered air, may perform
humidification to provide moisture, and may discharge humidified
air to the outside.
The air wash module 200 may include a water tank 300 for storing
water. The water tank 300 may be separable from the air clean
module 100 when the air wash module 200 is separated. The air wash
module 200 may be disposed over the air clean module 100.
A user can separate the air wash module 200 from the air clean
module 100, and can clean the air wash module 200 that is
separated. A user may also clean the inside of the air clean module
100 from which the air wash module 200 is separated. When the air
wash module 200 is separated, the upper surface of the air clean
module 100 may be opened to a user. The air clean module 100 may be
cleaned after separately removing a filter assembly 10 described
later.
A user may supply water into the air wash module 200. The air wash
module 200 may have a water supply flow passage formed therein to
supply water from the outside to the water tank 300.
The water supply flow passage may be configured to supply water
into the water tank 300 at any moment. For example, even when the
air wash module 200 is operating, water can be supplied through the
water supply flow passage. For example, even when the air wash
module 200 is coupled to the air clean module 100, water can be
supplied through the water supply flow passage. For example, even
when the air wash module 200 is decoupled from the air clean module
100, water can be supplied through the water supply flow
passage.
The air clean module 100 and the air wash module 200 may be
connected to each other through a connection flow passage 103.
Since the air wash module 200 is separable, the connection flow
passage 103 may be distributedly formed at the air clean module 100
and the air wash module 200.
The connection flow passage formed in the air clean module 100 may
be defined as a clean connection flow passage 104, and the
connection flow passage formed in the air wash module 200 may be
defined as a humidification connection flow passage 105. When the
air wash module 200 is mounted on the air clean module 100, for the
first time, the connection flow passage may be connected and the
flow passage of air may be configured accurately.
The flow of air passing through the air clean module 100 and the
air wash module 200 will be described in more detail later.
A configuration of the air clean module 100 will be described in
more detail as follows.
The air clean module 100 may include a base body 110 where an
intake flow passage 101 and a clean connection flow passage 104 are
formed, a filter assembly 10 disposed detachable from the base body
110 and performing filtration on flowing air, and an air blowing
unit 20 disposed inside the base body 110 and flowing air.

further moved to the lower side.
An air cleaner according to this embodiment may receive power
through the air clean module 100 and provide power to the air wash
module 200 through the air clean module 100. Since the air wash
module 200 has a structure separable from the air clean module 100,
the air clean module 100 and the air wash module 200 may be
provided with a separable power supply structure.
Since the air clean module 100 and the air wash module 200 are
assembled through the upper body 120, a connector 260 may be
disposed in the upper body 120 to provide power for the air wash
module 200. A top connector 270 may be disposed in the top cover
assembly 230, and may be separably connected to the connector 260.
When the top cover assembly 230 is placed, the top connector 270
may be disposed over the connector 260. The top cover assembly 230
may be supplied with electricity from the connector 260 via the top
connector 270.
The filter assembly 10 may be assembled to be detachable from the
base body 110.
The filter assembly 10 may provide the filtering flow passage 102,
and may filter external air.
The filter assembly 10 may have a structure that is detachable from
the base body 110 in a horizontal direction. The filter assembly 10
may be disposed so as to cross the flowing direction of air that
flows upstream in a vertical direction. The filter assembly 10 may
be disposed in a horizontal direction orthogonal to the flow of air
flowing from the lower side to the upper side.
The filter assembly 10 may slide in a horizontal direction with
respect to the base body 110.
The air blowing unit 20 may generate flowing of air. The air
blowing unit 20 may be disposed inside the base body 110, and may
allow air to flow from the lower side to the upper side.
The air blowing unit 20 may include a blower housing 150, a blower
motor 22, and a blower fan 24. In this embodiment, the blower motor
22 may be disposed at an upper side, and the blower fan 24 may be
disposed at a lower side. The blower motor 22 may include a blower
motor axis 23 and the blower motor axis 23 may be installed
downwardly and a blower fan 24 may be coupled to the blower motor
axis 23.

may be coupled to the water tank 300, and may be formed of a
transparent material. The top cover assembly 230 may be detachably
disposed over the visual body 210, and may include a discharge flow
passage 107 through which air is discharged and a water supply flow
passage 109 through which water is supplied.
The water tank 300 may be mounted on the upper body 120. The
watering unit 400 may be disposed inside the water tank 300, and
may rotate inside the water tank 300.
The watering unit 400 may draw water inside the water tank 300,

A display module 160 may be disposed outside the visual body 210.
The display module 160 may be coupled to any one of the visual body
210 and the upper body 120. In this embodiment, the display module
160 may be disposed at the upper body 120.
When the air wash module 200 is placed, the outer surface of the
visual body 210 may adhere closely to the display module 160. At
least a portion of the surface of the display module 160 may be
formed of a material that reflects light.
Droplets formed on the visual body 210 may also be projected onto
the surface of the display module 160. Accordingly, a user can
observe the motion of droplets at both visual body 210 and display
module 160.
The water tank 300 may include a water tank inlet 31 through which
air passes. The air supplied from the air clean module 100 may flow
into the air wash module 200 through the water tank inlet 31.
The humidification medium 50 may include a water tank
humidification medium 51 disposed at the connection flow passage
103, and a discharge humidification medium 55 disposed at the
discharge flow passage 107.
The water tank humidification medium 51 may be disposed on the
connection flow passage 103 and in this embodiment, may be disposed
at the water tank inlet 31 of the water tank 300. The water tank
humidification medium 51 may be disposed inside the water tank
inlet 31 and provide humidification on air passing through the
water tank inlet 31.
The water tank humidification medium 51 may cover the water tank
inlet 31, and air may penetrate the water tank humidification
medium 51 to flow into the water tank 300.
The discharge humidification medium 55 may be disposed on the
discharge flow passage 107. The discharge humidification medium 55
may be disposed on at least one of the visual body 21 or the top
cover assembly 230. In this embodiment, the discharge
humidification medium 55 may be disposed at the top cover assembly
230.
The discharge humidification medium 55 may cover the discharge flow
passage 107, and air may penetrate the discharge humidification
medium 55 to flow to the outside of the top cover assembly 230.
Hereinafter, the flow of air will be described with reference to
the accompanying drawings.
When the air blowing unit 20 operates, external air may flow into
the base body 110 through the intake flow passage 101 formed at a
lower side of the base body 110. Air entered through the intake
flow passage 101 may pass the air clean module 100 and the air wash
module 200 while moving upward, and may be discharged to the
outside through the discharge flow passage 107 formed at an upper
side of the air wash module 200.
The air entered to the intake flow passage 101 may pass through the
filtering flow passage 102 of the filter assembly 10. As the air
passes through the filtering flow passage 102, the filter assembly
10 may filter external air.
Air passing the filtering flow passage 102 may flow to the
connection flow passage through the air blowing unit 20. After the
air passing through the filtering flow passage 102 is pressed by
the blower fan 24, it flows to the connection flow passage 103
along the blower fan housing 150.
Since the air blowing unit 20 is disposed next to the filtering
flow passage 102, adherence of foreign substances like dust on the
blower fan 24 can be minimized.
If the air blowing unit 20 is disposed before the filtering flow
passage 102, foreign substances may be attached to the blower fan
24, and due to this, a cleaning cycle may be shortened.
Also, since the air blowing unit 20 is disposed at the front of the
humidification flow passage 106, adherence of moisture on the
surface of the blower fan 24 can be minimized. When moisture
adheres to the surface of the blower fan 24, foreign substances may
adhere to the surface of the blower fan 24 or molds may be likely
to grow on the blower fan 24.
Since the air blowing unit 20 is disposed between the filtering
flow passage 102 and the humidification flow passage 106, the
adherence of foreign substances may be minimized and the flow
pressure of air may be provided appropriately.
The connection flow passage 103 may include the clean connection
flow passage 104 formed in the air clean module 100 and the
humidification connection flow passage 105 formed in the air wash
module 200.
When the air wash module 200 is placed on the upper body 120, the
clean connection flow passage 104 and the humidification connection
flow passage 105 may be connected to each other. When the air wash
module 200 is in a separated state, the clean connection flow
passage 104 and the humidification connection flow passage 105 may
be exposed to the outside.
The clean connection flow passage 104 may be formed in the upper
body 120, and the humidification connection flow passage 105 may be
formed in the air wash module 200.
The clean connection flow passage 104 and the humidification
connection flow passage 105 may also be formed in a form of duct to
form a clear flow passage. In this embodiment, when the connection
flow passage 103 is distributed as a partial structure of the upper
body 120 and a partial structure of the water tank 300 and the air
wash module 200 is mounted on the upper body 120, the connection
flow passage 103 may be formed.
In this embodiment, the upper body 120 may provide the outer
structure of the connection flow passage 103 and the water tank 300
may provide the inner structure of the connection flow passage
103.
That is, the connection flow passage 103 may be formed between the
outside of the water tank 300 and the inside of the upper body 120.
Therefore, the connection flow passage 103 may be formed between
the water tank 300 and the upper body 120. The water tank 300 may
form an inner wall of the connection flow passage 103 and the upper
body 120 may form an outer wall of the connection flow passage
103.
In such a manner, the structure of the connection flow passage 103
may minimize a structure for forming a flow passage through a
distributed arrangement. The connection flow passage 103 may be
formed in a vertical direction.
Air passing through the connection flow passage 103 may flow into
the humidification flow passage 106. The humidification flow
passage 106 may be a section where moisture is supplied. In this
embodiment, the humidification flow passage 106 may be a flow
passage from the water tank humidification medium 51 to the
discharge humidification medium 55.
While air passes through the water tank humidification medium 51,
moisture may be supplied to the air in the connection flow passage
51. Then, water drops scattered from the watering unit 400 and
moistures evaporated from the water tank 300 may be provided into
the water tank 300.
As air passes through the discharge humidification medium 55,
moisture may be supplied again to the air in the water tank
300.
Moisture may be supplied in the humidification flow passage 106
through the water tank humidification medium 51, the inside of the
water tank 300, and the discharge humidification medium 55.
Air passing through the discharge humidification medium 55 may be
exposed to the outside through the discharge flow passage 107.

Referring to the drawings, the water tank 300 may include a water
tank body 320 for storing water, a water tank base 340 coupled to
the lower part of the water tank body 320, a water tank inlet 31
formed at a side surface of the water tank body 320, a column 35
disposed inside the water tank body 320 and protruding upwardly,
and a floater housing 330 disposed inside the water tank body 320
and including a floater 332 that moves in a vertical direction.
In this embodiment, the water tank body 320 may be formed into a
cylindrical shape with an opened upper side. Unlike this
embodiment, the water tank body 320 may be formed into various
shapes.
The column 35 may be formed at the water tank body 320, and a power
transmission module 60 described later may be disposed inside the
column 35. The column 35 may prevent or suppress the water stored
in the water tank body 320 from contacting the power transmission
module 60.
The water tank base 340 may be coupled to the outer undersurface of
the water tank body 320. A predetermined space may be formed
between the water tank base 340 and the water tank body 320. The
space formed between the water tank body 320 and the water tank
base 340 may be defined as a water tank base space 311. The water
tank base space 311 may be sealed from the outside and may be
configured to prevent water penetration.
The water tank body extension part 380 may upwardly extend from the
water tank 300. The water tank body extension part 380 may form the
water tank inlet 31. The water tank inlet 31 may be formed between
the water tank body extension parts 380.
The water tank inlet 31 may be formed in the side surface of the
water tank body 320. The water tank inlet 31 may be formed in all
directions of 360 degrees of a circumference the water tank body
320. The water tank inlet 31 may communicate with the connection
flow passage 103.
The water tank body extension part 380 may guide water flowing down
from the inner side surface of the visual body 210 into the water
tank 300. The noise of dropping water can be minimized by guiding
water flowing down from the visual body 210.
The water tank body extension part 380 may be fastened to the lower
end of the visual body 210. A water tank fastening part 381
fastened to the visual body 210 may be disposed on at least one of
the plurality of water tank body extension parts 380. The water
tank fastening part 381 may be disposed outside the water tank body
extension part 380. The visual body 210 and the water tank 300 may
be coupled to each other through a fastening member (not shown)
fastened to the water tank fastening part 381.
The column 35 may be disposed at the water tank body 320. In this
embodiment, the column 35 may be formed in a conical shape. The
watering housing 800 may be installed to surround the column 35. In
this embodiment, the column 35 may be integrally formed with the
water body 320. The column 35 may be formed protruding upwardly
from the undersurface of the water tank body 320.
The floater housing 330 may be formed inside the water tank body
320. The floater 322 may be disposed inside the floater housing
330. The floater 332 may be formed of a material having a lighter
specific gravity than water and move vertically according to a
level of water stored in the water tank 300 inside the floater
housing 330.
The floater housing 330 may be installed at the inner sidewall of
the water tank body 320. The floater housing 330 may extend long in
a vertical direction. The floater housing 330 may have a structure
where water of the water tank body 300 flows.
The lower end 331 of the floater housing 330 may protrude
downwardly from the undersurface of the water tank body 320. A
space formed protruding toward the lower side of the water tank
body 320 may be defined as a floater storage space 333.
When the floater 332 is located in the floater storage space 333,
it may be a state that there is no water in the water tank 300.
The floater 332 may be part of a water level sensor. A permanent
magnet 335 may be disposed at the floater 332. The water level
sensor may include a magnetic sensor 334 for detecting the magnetic
force of the permanent magnet 335. The magnetic sensor 334 may be
disposed at the upper body 120.
Therefore, the water level sensor may detect a water level of the
water tank 300 in a non-contact method. Especially, since the water
tank 300 is a separable structure, it may be desirable to detect a
water level through a non-contact method. Whether the water tank
300 is mounted may be determined by using a signal detected from
the water level sensor. For example, when the magnetic sensor 334
detects the permanent magnet, a controller (not shown) may
determine that the water tank 300 is mounted.
The water tank base 340 may include a base border 342 protruding
upwardly from the undersurface, and a groove 343 where the lower
end 331 of the floater housing 330 is inserted may be formed in the
base border 342. The lower end 331 may be inserted into the groove
343. The lower end 331 may be exposed through the groove 343. The
lower end 331 of the floater housing 330 exposed through the groove
343 may allow easy detection of the magnetic sensor 334.
When the lower end 331 is surrounded by the base border 342, a
magnetic field signal for the permanent magnet may be reduced and
due to this, incorrect detection may occur.
By exposing the lower end 331 through the groove 343, the permanent
magnet of the floater 332 located inside the lower end 331 may be
easily detected.
A configuration for improving the rigidity of the water tank 300
may be disposed in the water tank body 320 and the water tank base
340. The water tank 300 may be used as a space for storing water
and also may support the watering unit 400 rigidly. Through this,
the water tank 300 should suppress vibration occurring from the
watering unit 400.
When the watering unit 400 is not supported sufficiently, the floor
301 of the water tank body 320 may be changed or shaken, and
vibration may occur. The vibration occurring from the water tank
300 may spread throughout the entire structure and therefore, an
adverse effect on the entire humidification and air cleaning
apparatus may occur.
In order to minimize this, a configuration for improving the
rigidity may be disposed in the water tank body 320 and the water
tank base 340.
The undersurface of the column 35 formed at the water tank body 320
may be open. The open undersurface of the column 35 may be referred
to as a water tank body insertion hole 329. A bearing housing 650
described later may be inserted through the water tank body
insertion hole 329. The bearing housing 650 may be a composition of
the power transmission module 600.
The base insertion hole 349 may be formed inside the water tank
base 340. The base insertion hole 349 may be disposed at the lower
side of the water tank body insertion hole 329. The bearing
insertion hole 349 may be located at the lower side of the bearing
housing 650.
The lower part of the bearing housing 650 may be exposed through
the base insertion hole 349. A first coupler 610 described later
may be inserted into the base insertion hole 349.
The bearing housing 659 may include a bearing housing body 652
inserted into the column 35 and a housing flange 654 formed at the
lower end of the bearing housing body 652 and closely contacting
the undersurface of the water tank body 320.
The lower surface of the bearing housing 650 may be formed open.
The open undersurface of the hearing housing 650 may be referred to
as a bearing housing insertion hole 659. A second coupler 620
described later may be disposed in the bearing housing insertion
hole 659.
The bearing housing insertion hole 659 and the base insertion hole
349 may communicate with each other.
The base insertion hole 349 may be located at the lower side of the
bearing housing insertion hole 659. The second coupler 620 may be
exposed through the base insertion hole 349. The first coupler 610
may be inserted through the base insertion hole 349 and may be
detachably coupled to the second coupler 620.
The housing flange 654 may be formed to the outside in a radial
direction. The housing flange 654 may closely contact the lower
undersurface of the water tank body 320. When seen from a plane,
the housing flange 654 may be formed wider than the plane of the
column 35.
The column 35 and the housing flange 654 may be disposed on the
concentric axis.
The housing flange 654 may be fastened to the water tank 300
through a fastening member 651. The fastening member 651 may be
fastened to the water tank body 320 through the housing flange
654.
Separately from a first fastening member 651 for fixing the bearing
housing 650, a fastening member 655 for fixing the water tank body
320 and the water tank base 340 may be disposed.
The fastening member 651 for fixing the bearing housing 650 may be
defined as the first fastening member 651 and the fastening member
655 for fixing the water tank body 320 and the water tank base 340
may be defined as a second fastening member.
In this embodiment, the first fastening member 651 may fasten the
water tank base 340, the housing flange 654, and the water tank
body 320 at a time. Since the first fastening member 651 fastens
three compositions at the same time, the bearing housing 650 may be
more robustly fixed. Since the first fastening member 651 fastens
three compositions at the same time, the lower rigidity of the
water tank 300 may be improved.
In order to install the first fastening member 651, fastening parts
321 and 341 may be formed at the water tank body 320 and the water
tank base 340, respectively.
A body fastening part 321 formed at the water tank body 320 may be
formed in a boss shape, and base fastening part 341 formed at the
water tank base 340 may be formed in a hole shape.
A flange fastening part 653 that the first fastening member 651
penetrates may be formed at the housing flange 654. The flange
fastening part 653 may be in a hole shape.
The first fastening member 651 is a screw and is fixed to the body
fastening part 321 through the base fastening part 341 and the
housing flange 654. The first fastening member 651 is fastened to
the upper side at the lower side.
Each of the first fastening member 651 and the fastening parts 341,
653, and 321 may be formed in plurality. The first fastening member
651 may be disposed at least two, and in this embodiment, four may
be radially disposed based on the power transmission axis 640.
When seen from a plane, the first fastening member 651 may be
disposed at 90-degree equal intervals on the basis of the power
transmission axis 640. Separately from a first fastening member 651
for fixing the bearing housing 650, a fastening member 655 for
fixing the water tank body 320 and the water tank base 340 may be
disposed.
The first fastening member 651 for fixing the bearing housing 650
may be defined as the first fastening member 651 and the fastening
member 655 for fixing the water tank body 320 and the water tank
base 340 may be defined as a second fastening member 655.
The fastening member 655 may improve the rigidity of the water tank
300 by coupling the water tank body 320 and the water tank base
340.
The second fastening member 655 is for coupling the water tank body
320 and the water tank base 340. Unlike this embodiment, through a
mutual catch through a hook instead of a fastening member, a water
tank body and a water tank base may be coupled to each other. When
coupling is implemented through a mutual catch, since a fine
interval is formed, it may be vulnerable to vibration. In this
embodiment, in order to prevent this, the water tank body 320 and
the water tank base 340 are coupled to each other through the
second fastening member 655.
The second fastening member 655 may be fastened at the lower part
of the water tank base 340 and fastened to the water tank body 320
through the water tank base 340. A fastening part 325 to which the
second fastening member 655 is fastened may be formed at the
undersurface of the water tank body 320.
A fastening part 321 coupled to the first fastening member 651 may
be defined as a first fastening part 321. A fastening part 325
coupled to the second fastening member 655 may be defined as a
second fastening part 325. A fastening part 341 formed at the water
tank base 340 may be defined as a base fastening part 341.
The second fastening part 325 may be formed protruding downwardly
from the undersurface of the water tank body 320. The second
fastening part 325 may be formed in a boss shape.
The second fastening part 325 may be disposed radially on the basis
of the power transmission axis 640. The second fastening part 325
may be disposed in plurality around the power transmission axis 640
and each may be disposed at an equal interval. In this embodiment,
six second fastening parts 325 may be disposed at 60-degree equal
intervals on the basis of the power transmission axis 640.
Through the second fastening member 655, the water tank base 340
may closely contact the undersurface of the water tank body 320 and
may be fixed to it, and also may closely contact the housing flange
654.
A flange supporter 348 for supporting the housing flange 654 may be
formed at the water tank base 340. The flange supporter 348 may
protrude upwardly.
The flange supporter 348 may be formed around the base insertion
hole 349. In this embodiment, the flange supporter 348 may be
formed circularly along the base insertion hole 349.
The base fastening part 341 may be disposed outside the flange
supporter 348. That is, when the flange supporter 348 supports the
bearing housing 650, the first fastening member 651 may fasten the
water tank base 340, the housing flange 654, and the water tank
body 320.
Moreover, ribs for improving each strength may be disposed at the
water tank body 320 and the water tank base 340.
A rib formed at the water tank 320 in order for strength
enhancement may be referred to as a body enhancement rib 350 and a
rib formed at the water tank base 340 may be referred to as a base
enhancement rib 355.
The body enhancement rib 350 may be formed at the floor 301 of the
water tank body 320. The body enhancement rib 350 may be formed
protruding downwardly from the undersurface of the water tank body
320.
The body enhancement rib 350 may include a first enhancement rib
352 formed radially based on the power transmission axis 640 and a
second enhancement rib 354 formed circumferentially based on the
power transmission axis 640.
The first enhancement rib 352 may be formed extending from the
water tank body insertion hole 329 to the edge. The first
enhancement rib 352 may be radially formed in plurality.
The second enhancement rib 354 may be disposed to form a concentric
circle to the outside in a radial direction from the water tank
body insertion hole 329. The second enhancement rib 354 may be
disposed in plurality to the outside in a radial direction while
forming a concentric circle.
The first enhancement rib 352 and the second enhancement rib 354
may intersect each other.
Through the first enhancement rib 352 and the second enhancement
rib 354, a thickness of the water tank body 320 may be minimized
and its strength may be maintained with the minimized
thickness.
Through the first enhancement rib 352 and the second enhancement
rib 354, it may be minimized that the vibration of the bearing
housing 650 is delivered to the outside of the water tank 300 in a
radial direction.
Through the first enhancement rib 352 and the second enhancement
rib 354, eccentricity may be minimized during an operation of the
watering unit 400. Since the watering unit 400 extends long in a
vertical direction, when the strength of the floor 301 of the water
tank 300 is enhanced, eccentricity may be minimized at the upper
end of the watering unit 400.
The base enhancement rib 355 may be formed along the edge of the
water tank base 340.
A groove 356 concaved in a vertical direction may be formed in the
water tank base 340, and the base enhancement rib 355 may be formed
at the groove 356.
The groove 356 may be formed along the edge of the water tank base
340. The groove 356 may form a closed curve when seen from the
undersurface of the water tank base 340.
The base enhancement rib 355 may be disposed in plurality along the
groove 356.
Moreover, a sealing structure for suppressing water penetration may
be disposed between the water tank body 320 and the water tank base
340.
A first packing for sealing the inner edges of the water tank body
320 and the water tank base 340 and a second packing 362 for
sealing the outer edges of the water tank body 320 and the water
tank base 340 may be disposed.
The first packing 361 may prevent water or moisture from entering
through the base insertion hole 349. The second packing 362 may
prevent water or moisture from entering through the outer edges of
the water tank body 320 and the water tank base 340.
In order to install the first packing 361, a first packing
installation groove 363 may be disposed. The first packing

first packing installation groove 363 may be formed at the
undersurface of the housing flange 654. The first packing
installation groove 363 may form a closed curve around the base
insertion hole 349.
The first packing installation groove 363 may be formed concave
upwardly. When the flange supporter 384 closely contacts the
housing flange 654, sealing is implemented as the first packing 361
closely contacts it.
Moreover, a packing 365 may be installed between the housing flange
654 and the water tank body 320. The packing 365 may be disposed at
the upper side of the housing flange 654. The packing 365 may seal
the water tank body insertion hole 329. The packing 365 may form a

Also, in order to install the second packing 362, a second packing
installation groove 364 may be disposed.
The second packing installation groove 364 may be disposed in at
least one of the water tank body 320 and the water tank base 340.
In this embodiment, it may be formed at the upper surface of the
water tank base 340. The second packing installation groove 364 may
be formed concave downwardly.
The second packing installation groove 364 may form a closed curve
along the edge of the water tank base 340. The second packing
installation groove 364 may be formed by a rib 367 protruding
upwardly from the upper surface of the water tank base 340.
In this embodiment, the second packing installation groove 364 may
be located at the upper side of the base enhancement rib 355. The
second packing installation groove 364 may be disposed at the upper
side of the groove 356 where the base enhancement rib 355 is
disposed.
That is, the groove 356 and the second packing installation groove
364 for the base enhancement rib 355 may be disposed vertically and
through this, the second packing installation groove 364 may
enhance the strength.
The second packing installation groove 364 may be formed as
avoiding the lower end 331 of the floater housing 330. The lower
end 331 of the floater housing 330 may be located outside the
packing installation groove 364.
Moreover, a window module 390 may be installed at the undersurface
of the water tank 300 to transmit light. The window module 390 may
transmit ultraviolet rays.
A body opening part 326 may be formed at the water tank body 320. A
base opening part 346 may be formed in the water tank base 340. The
base opening part 346 may be located at the lower side of the body
opening part 326. The body opening part 326 and the base opening
part 346 may be disposed in a vertical direction.
The window module 390 may be disposed between the water tank body
320 and the water tank base 340. The window module 390 may closely
contact between the water tank body 320 and the water tank base
340.
In this embodiment, the window module 390 may be fastened to the
undersurface of the water tank body 320 and seal the body opening
part 326.
In relation to the window module 390, an ultraviolet module 290 for
providing ultraviolet rays may be disposed at the upper body 120.
Ultraviolet rays generated from the ultraviolet module 190 may
penetrate the window module 390 to be projected into the water tank
300. The water stored in the water tank 300 may be sterilized
through the ultraviolet rays.
Then the flow guide 310 formed at the undersurface of the water
tank 300 will be described.
The flow guide 310 for guiding the stored water to the watering
housing 80 may be disposed at the undersurface of the water tank
300. The flow guide 310 may be formed integrally with the water
tank 300. In this embodiment, the flow guide 310 may be formed
integrally with the water tank body 320. The flow guide 310 may be
formed protruding upwardly from the undersurface of the water tank
body 320.
The case that the water stored in the water tank 300 may be defined
as empty water. The empty water may be greater than the minimum
amount for spraying water through the watering housing 800.
The empty water may be a height from the inner undersurface of the
water tank 300.
When the watering housing 800 stops, the height of stored water may
be an amount for spraying water through a nozzle 410 but after the
watering housing 800 rotates, the water height may be lower than
the suction interval 801.
This is because that the central water moves toward the inner
sidewall of the water tank 300 by the rotation of the watering
housing 800. The flow guide 310 may be for suppressing such a water
concentration.
When water stored in the water tank 300 is empty, the flow guide
310 may improve the drawing efficiency of the water housing 800.
The flow guide 310 may provide a flow in a rising direction with
respect to the water rotating inside the water tank 300.
Additionally, the flow guide 310 may guide water rotating in the
water tank 300 toward the watering housing 800.
The flow guide 310 may guide water flowing along the inner side of
the water tank 300 toward the center where the watering housing 800
is located. The flow guide 310 may form a minimum separation
distance (for example, 5 mm) to the watering housing 800. The flow
guide 310 may provide effects such as empty water efficiency
improvement, nose reduction, and vibration reduction.
The flow guide 310 may be spaced a predetermined interval away from
the inner wall of the water tank body 320.
When the water of the water tank 300 rotates by the watering
housing 800, the flow velocity of the water rotating in a close
distance to the watering housing 800 may be different from the flow
velocity of the water rotating along the inner wall of the water
body 320.
The flow guide 310 may allow a flow velocity in the water tank 300
to be uniform. For this, when seen on a plane, an angle between the
length direction of the flow guide 310 and the outer side surface
of the watering housing 800 may be formed within 90 degrees.
The flow guide 310 may include a first inclination surface 312 and
a second inclination surface 314.
The first inclination surface 312 may be formed toward the flow
direction of water. Rotating water may be received through the
first inclination surface 312. Water rotating along the first
inclination surface 312 may be railed upwardly. The first
inclination surface 312 may guide water rotating along the inner
edge of the water tank 300 toward the watering housing 800.
The second inclination surface 314 may be formed opposite to the
first inclination surface 314. A boundary 315 where water overflows
may be formed between the first inclination surface 312 and the
second inclination surface 314. When seen on a plane, in this
embodiment, the boundary 315 may be disposed in a tangential
direction with respect to the surface of the watering housing
800.
The flow guide 310 may provide an effect with only one. In this
embodiment, the flow guide 310 may be disposed in two.
Then, a watering unit 400 disposed inside the water tank 300 will
be described.
The watering unit 400 may rotate the watering housing 800 disposed
inside the water tank 300 and spay water stored inside the water
tank 300 to the inner side surface of the visual body 210 through
the rotation of the watering housing 800.
The watering unit 400 may provide a structure for rotating the
watering housing 800. The watering unit 400 may provide a power
transmission module 600 for delivering power to the watering
housing 800 in a separable structure of the water tank 300 and the
upper body 120.
A structure of the watering unit 400 will be described in more
detail as follows.
The watering unit 400 may include the watering housing 800, a
watering motor 42, and the power transmission module 600.
The power transmission module 600 may include a watering housing
800 disposed inside the water tank 300, drawing the water of the
water tank as rotating, pumping the drawn water upwardly, and
discharging the pumped water to the outside, a watering motor 42
for providing a torque to the watering housing 800, and a power
transmission module 600 for delivering a torque of the watering
motor 42 to the watering housing 800.
After pumping the water stored in the water tank 300 upwardly, the
watering housing 800 may have a configuration for spraying the
pumped water to the outside in a radial direction.
The watering motor 42 may have a configuration for providing a
torque for rotating the watering housing 800.
The power transmission module 600 may have a configuration for
transmitting a torque of the watering motor 42 to the watering
housing 800.
The watering housing 800, the watering motor 42, and the power
transmission module 600 may be all installed at the water tank 300.
In this case, a user may be required to lift the watering motor 42
when separating the air wash module 200. Additionally, in a case
that even the watering motor 42 is assembled to the air wash module
200, if the air wash module 200 is required to be separated from
the air clean module 200, the power supply structure of the
watering motor 42 should be separable.
Therefore, this embodiment may suggest a structure where the heavy
watering motor 42 is disposed at the upper body 120 and only the
watering housing 800 and the power transmission module 600 are
separated. A structure as in this embodiment may minimize the
weight of the separable air wash module 200.
In this embodiment, the watering housing 800 and the watering motor
42 may be separable. The watering housing 800 may be installed
inside the air wash module 200, and the watering motor 42 may be
installed inside the air clean module 100. When the air wash module
200 is separated, the watering housing 800 may be separated from
the air clean module 100 together with the water tank 300.
In order for a separation structure of the watering housing 800 and
the watering motor 42, in this embodiment, the power transmission
module 500 may be designed to be separable.

300 may be inserted into the upper body 120.
The upper body 120 may support the load of the air wash module 100.
Especially, the water tank 300 may be mounted on the upper body 120
and the water tank 300 and the upper body 120 may contact each
other.
A vibration insulation member 370 may be disposed between the water
tank 300 and the upper body 120. The vibration insulation member
370 may separate the water tank 300 and the upper body 120 by a
predetermined interval, and vibration-isolate the water tank 300
and the upper body 120.
That is, the vibration insulation member 370 may prevent vibration
between the water tank 300 and the upper body 120. The vibration
insulation member 370 may separate the water tank 300 and the upper
body 120 by a predetermined interval.
The vibration insulation member 370 may be formed of an elastic
material. The vibration insulation member 370 may be disposed on at
least one of the water tank 300 and the upper body 120.
In this embodiment, the vibration insulation member 370 may be
disposed at the upper body 120 and support the water tank 300.
The vibration insulation member 370 may be disposed inside the
upper body 120 and protrude a predetermined height from the bottom
of the upper body 120. The vibration insulation member 370 may
support the load of the air wash module 200 including the water
tank 300.
The vibration insulation member 370 may prevent the vibration of
the air clean module 100 from being delivered to the air wash
module 200. The vibration insulation member 370 may prevent the
vibration of the blower fan 24, the blower motor 22, and the
watering motor 42, disposed at the air clean module 100, from being
delivered to the air wash module 200.
Additionally, the vibration insulation member 370 may prevent the
vibration of the watering unit 400 of the air wash module 200 from
being delivered to the upper body 120.
Trough the vibration isolation of the vibration insulation member
370, vibration may be prevented from being delivered and vibration
noise may be reduced.
Additionally, trough the vibration isolation of the vibration
insulation member 370, resonance occurrence may be greatly
reduced.
Hereinafter, a structure of the upper body 120 will be described in
more detail.
The upper body 120 may include an upper outer body 128 forming the
exterior of the base body and coupled to the lower body 130, an
upper inner body 140 disposed inside the upper outer body 128,
having the water tank 300 inserted therein, and providing the
connection flow passage 103, and an air guide 170 coupling the
upper inner body 140 and the upper outer body 128 and guiding air
to the water tank 300.
The upper inner body 140 may be formed to be opened at the upper
side thereof, and may receive the water tank 300. The upper inner
body 140 may form a portion of the clean connection flow passage
104 into which filtered air flows.
The upper inner body 140 may have an upper inlet 121 formed therein
and corresponding to a water tank inlet 31. The upper inlet 121 may
not be an essential component. It may be sufficient if the upper
body 120 has a shape that exposes the water tank inlet 31 to the
connection flow passage 103.
The air guide 170 may guide air supplied through the clean
connection flow passage 104 to the upper inlet 121. The air guide
170 may collect air rising along the outside of the base body 110
toward the inside. The air guide 170 may change the flowing
direction of air flowing from the lower side to the upper side.
However, the air guide 170 may minimize the flow resistance of air
by minimizing the change angle of the flow direction of air.
Accordingly, the air guide 170 may include a guide part 172 formed
in the flowing direction of air, and a change part 174 that is
connected to the guide part 172 and changes the flow direction of
guided air.
The air guide 170 may form the connection flow passage 103.
The guide part 172 may be formed in the substantially same
direction as the filtering flow passage 102, and in this
embodiment, may be formed in a vertical direction. The change part
174 may be formed in a direction crossing the filtering flow
passage 102, and in this embodiment, may be formed in a
substantially horizontal direction.
The change part 174 may be disposed at an upper side of the air
guide 170. The change part 174 may be connected to the guide part
172 through a curved surface.
Although the change part 174 is formed in a horizontal direction,
air passing the connection flow passage 103 may upwardly flow in a
substantially oblique direction. The flow resistance of air can be
reduced by forming an angle between the connection flow passage 103
and the filtering flow passage 102 to be close to 180 degrees.
The lower end of the guide part 172 may be fixed to the upper outer
body 128. The upper end of the change part 174 may be fixed to the
upper inner body 140.
A portion of the clean connection flow passage 104 may be formed
outside the upper inner body 140. The air guide 170 may form a
portion of the clean connection flow passage 104. Air passing the
clean connection flow passage 104 may flow into the water tank 300
through the upper inlet 121 and the water tank inlet 31.
The upper inner body 140 may have a basket shape on the whole. The
upper inner body 140 may have a circular shape in horizontal
section, and the clean connection flow passage 104 may be formed in
all directions of 360 degrees of a circumference of the upper inner
body 140.
The upper inner body 140 may have the inside in a concave form and
surround the outside of the water tank 300. The vibration
insulation member 370 may be disposed at the bottom 141 of the
upper inner body 140.
The vibration insulation member 370 may protrude a predetermined
height from the bottom 141 of the upper inner body 120. The
vibration insulation member 370 may be formed of a different
material than the upper inner body 140.
The upper inner body 140 may have an insertion groove 142 where the
vibration insulation member 370 is inserted.
The insertion groove 142 may be disposed outside a first coupler
610. The insertion groove 142 may be disposed in plurality. The
insertion groove 142 may be disposed in a circumferential direction
on the basis of the watering motor axis 43. The insertion groove
142 may be disposed symmetrically on the basis of the watering
motor axis 43. The insertion groove 142 may be formed protruding
downwardly from the bottom 141. The insertion groove 142 may be
formed concave downwardly from the upper side.
Moreover, a fastening member 147 for fixedly fastening the upper
body 120 and the lower body 130 may be disposed and the fastening
member 147 may be installed at the insertion groove 142.
The lower end of the insertion groove 142 may be supported by a
structure of the lower body 130. The fastening member may penetrate
the lower end of the insertion groove 142 to be fastened to the
lower body 130.
A hole 143 that the fastening member penetrates may be formed at
the lower end of the insertion groove 142. After inserted into the
insertion groove 142 at the upper side, the fastening member may be
fastened to the lower body 130.
After the fastening member 147 is fastened, the vibration
insulation member 370 may be insertingly installed to the insertion
groove 142. The vibration insulation member 370 may seal the
insertion groove 142. The exposure of the fastening member may be
prevented by sealing the insertion groove 142 and the fastening
member may be prevented from being exposed to water.
When the water of the water tank 300 overflows, the water may be
stagnated at the bottom of the upper inner body 140, and when the
fastening member 147 is exposed to the stagnated water, corrosion
may occur.
Additionally, when water is stagnated in a water tank insertion
space 125, water may be leaked into the lower body 130 through the
hole 143 of the insertion groove 142. Since a plurality of
electrical components are inside the lower body 130, flowing water
may be prevented.
Sealing an installation structure of the fastening member 147 may
be very important due to the above reason. In this embodiment,
through the vibration insulation member 370, the air wash module
200 and the air clean module 100 may be vibration-insulated and
also a coupling structure of the upper body 120 and the lower body
130 may be sealed.

may be disposed inside the sensor housing 336. The sensor housing
336 may be located inside the air guide 170 and disposed at a clean
connection flow passage 104.
The air guide 170 may be a component for guiding filtered air to
the clean connection flow passage 104, and may be omitted in
accordance with embodiments. The air guide 170 may combine the
upper inner body 140 or the upper outer body 128.
The air guide 170 may be formed to cover the upper inner body 140.
Particularly, the air guide 170 may be formed to cover the upper
inlet 121, and may guide filtered air to the upper inlet 121. When
viewed from top, the air guide 170 may have a donut shape.
In this embodiment, the upper end of the air guide 170 may adhere
closely to the upper end of the upper inner body 140.
When viewed from top, the upper side surface of the air guide 170
may coincide with the upper side surface of the upper inner body
140. In this embodiment, an upper inner body ring 126 may be
disposed on the upper end of the upper inner body 140 to be coupled

motors 22 and 42 operate at the same time, resonance and vibration
may be minimized. The blower motor 22 and the watering motor 42 may
be controlled separately.
Meanwhile, an outer visual body 214 may be coupled to the upper
side of the upper body 120.
The outer visual body 214 may be a component of the visual body
210, but in this embodiment, may be fixed to the upper body 120.
Unlike this embodiment, the outer visual body 214 may also be fixed
to the air wash module 200. Unlike this embodiment, the outer
visual body 214 may be omitted.
The outer visual body 214 may be fixed to the upper body 120. In

water drops formed on the visual body 210 may be projected onto or
reflected by the surface of the display housing 164. When the water
drops formed on visual body 210 flows down, the same effect is also
shown on the display housing 164.
This effect may give a visual stimulus to a user, and a user may
intuitively recognize that humidification is being performed. The
water drop image projected on the display housing 164 may give a
refreshment feeling to a user, and may allow a user to know the
humidification state.
The upper side surface of the display housing 164 may be obliquely
formed. The display housing 164 may be obliquely disposed toward a
user. Accordingly, the inside of the display 160 may be high, and
the outside thereof may be low.
FIG. 22 is a cross-sectional view of FIG. 1. FIG. 23 is an exploded
cross-sectional view when a watering motor and a blower motor are
separated. FIG. 24 is a cross-sectional view when a watering motor
and a blower motor are coupled.
Referring to the drawing, a coupling relationship and arrangement
of an upper body and a lower body will be described in more
detail.
A lower body 130 may include a lower outer body 138 for forming the
appearance of a base body 110 and a blower fan housing 150 disposed
inside the lower outer body 138.
The blower fan housing 150 may be disposed inside the lower outer
body 138 and coupled to the lower outer body 138.
The upper body 120 may include an upper outer body 128 forming the
appearance of the base body 110 and coupled with the lower outer
body 138 and an upper inner body 140 disposed inside the upper
outer body 128, including the water tank 300 inserted, and
providing a connection flow passage 103.
Herein, the upper outer body 128 and the lower outer body 138 may
be fastened to each other. The upper inner body 140 may be fastened
to the blower fan housing 150. In the fastening state, the watering
motor 42 and the blower motor 22 may form a motor separation
distance MD.
In order for the fastening of the upper outer body 128 and the
lower outer body 138, a fastening part 127 may be disposed at the
upper outer body 128 and a fastening part 137 may be disposed at
the lower outer body 138. Through the fastening parts 127 and 137,
the load may be supported.
In order for the fastening of the upper inner body 140 and the
blower fan housing 150, an insertion groove 142 may be formed at
the upper inner body 140 and a fastening part 152 may be disposed
at the blower fan housing 150.
Through the insertion groove 142 and the fastening part 152, the
load may be supported.
The watering motor 42 may be installed at the upper inner body 140
and the blower motor 22 may be installed at the blower fan housing
150.
Since the blower motor 22 and the watering motor 42 are disposed
spaced from each other, vibration may not be directly delivered.
Since the blower motor 22 and the watering motor 42 are disposed
spaced from each other, resonance occurrence may be minimized.
The vibration generated from the blower motor 22 may be delivered
to the watering motor 42 only when going through the blower fan
housing 150, the lower outer body 138, the upper outer body 128,
and the upper inner body 140.
On the other hand, the vibration generated from the watering motor
42 may be delivered to the blower motor 22 only when passing
through the upper inner body 140, the upper outer body 128, the
lower outer body 138, and the blower fan housing 150.
During the process of undergoing a plurality of structures,
vibration may be reduced and buffered.
Especially, a structure for suppressing vibration in such a manner
may minimize the vibration delivered to the water tank 300 mounted
in the water tank insertion space 300.
A humidification and air cleaning apparatus according to an
exemplary embodiment of the present invention has at least one of
the following effects.
First, since two motors form a motor separation interval, vibration
generated from one can be prevented from being directly delivered
to the other.
Second, since the motor separation interval is formed, even when
two motors operate at the same time, resonance occurrence can be
prevented.
Third, since blower motor and a watering motor are stacked
vertically inside a base body, eccentricity can be minimized.
Fourth, since a blower motor axis is installed downwardly and a
watering motor axis is installed upwardly, space can be utilized
efficiently.
Fifth, since a blower motor axis and a watering motor axis are
disposed on the same line, even if two of them operate at the same
time, eccentricity and vibration can be minimized.
The effects of the present invention are not limited to the above;
other effects that are not described herein will be clearly
understood by the persons skilled in the art from the following
claims.
While this invention has been particularly shown and described with
reference to preferred embodiments thereof, it will be understood
by those skilled in the art that various changes in form and
details may be made therein without departing from the spirit and
scope of the invention as defined by the appended claims. The
preferred embodiments should be considered in descriptive sense
only and not for purposes of limitation. Therefore, the scope of
the invention is defined not by the detailed description of the
invention but by the appended claims, and all differences within
